This is a mounting case/bezel for the D07 lights. This particular item is black in colour, and is a “horizontal” mount meaning that it orients the light so that it shines perpendicular to the mounting surface. For example, if the light and case were mounted to a horizontal desk surface, the light would shine sideways along the desk surface.
The bezels are also available in Vertical and 45 degree versions. They are available in Black, White, and Chrome (polished stainless steel).
D07 light is not included. Mounts with 2 screws.
